(-23%)4-Channel 12 V Relay Module with optocoupler isolation. Enables switching of four independent loads (up to 10 A each) using 12 V control signals, with LED indicators and screw-terminal connections.
Product details
This 4-channel relay module is powered from a 12 V DC supply and provides four separate electromechanical relays, each driven via an optocoupler-isolated input. The optocoupler isolation protects your control logic or microcontroller from voltage spikes, noise or ground-loop issues when driving inductive or high current loads.
Each relay channel supports up to 10 A switching current at standard AC or DC voltages, and has its own screw-terminal output (COM / NO / NC) and status LED. The control inputs accept 12 V logic or trigger signals and are isolated from the load side via optical isolation. Mounting holes on the PCB allow secure installation.
This module is ideal for embedded / industrial-lite automation, home / building control systems, robotics, IoT interfaces, or other applications where four independent outputs are required—while maintaining good electrical isolation and safety.
